KNOWPEIN

Here are some age facts from databook :-

kakashi graduated from academy at age 5(child prodigy)

obito and rin graduated at age 9

now considering genin team to be formed after graduation

so team minato had kakashi at age 5, rin and obito of age 9


this implies kakashi is at least 4 years younger than obito and rin

also guy graduate at age 7 from academy



next we come at chunnin graduation data





kakashi became chunin at age 6(after defeating 8 year old guy)
rin and obito both 10 yr old

obito and rin become chunnin at age 11(a year after kakashi)

guy also becomes chunin at age 11(but 3 years after kakashi)
so when guy becomes chunin kakashi obito amd rin are of age 9,12,12 respectively.





now comes greatest blunder
databook says obito died at age 13(2 years after his chunin exam)
and in kakashi gaiden kakashi is said to be of age 13(becoming jounin)
which leads to say obito must be at least 17....


the all loopholes arise from here
how come this happpen ?


before chapter 599 I assumed kakashi graduated and was assigned initially with some temprorary team untill being asigned with obito and rin who were supposed to be his age.


"Also Rin was attracted to a guy 4 years younger than her "
